Abstract
Disclosed are a single crystal wire and other single crystal articles, and a manufacturing method thereof. The method comprises the steps of: placing into a growth crucible at least one metal selected from the group consisting of gold, copper, silver, aluminum and nickel; heating and melting the metal placed in the growth crucible; growing a single crystal using metal crystal as a seed by Czochralski or Bridgman method; cutting the grown single crystal by electric discharge machining; and machining the cut single crystal and producing a wire or other articles such as a ring. In the method, the grown metal single crystal is cut into a disc-shaped piece by electric discharge machining. The piece is transformed into a single crystal wire or other articles by wire-cut electric discharge machining, and the single crystal wire can be used as a ring, a pendant, or a wire for high-quality cables for audio and video systems. Also, the single crystal formed into the disc-shaped piece by electric discharge machining can be used as a substrate and a target for deposition.
